night vision

Night vision is technology that provides users with some vision in total darkness and improved vision in low-light environments. 

The most common applications include night driving or flying, night security and surveillance, wildlife observation, sleep lab monitoring and search and rescue. Night vision is often used by the military and also has recreational purposes, like use on home video cameras or during night hiking.

The three main types of night vision technology are low-light imaging, thermal imaging and near-infrared illumination.
